Ingredients
Instructions
1. Preheat oven to 350°F (175°C) and line a cupcake pan with cupcake liners.
2. Whisk together the flour, cocoa powder, baking powder, and salt.
3. In another bowl whisk together the oil, granulated sugar, brown sugar, and egg until smooth.
4. Alternate adding half of the dry ingredients and half of the milk, mixing after each addition. Repeat with the remaining ingredients until just combined.
5. Fill the cupcake liners about three-quarters full and bake for 30–35 minutes. Cool completely.
6. Cut a small hole in the center of each cupcake and fill with warmed Nutella.
7. Beat the softened butter for 10 minutes, add powdered sugar and beat for 5 minutes, then add melted dark chocolate and beat until fluffy.
8. Pipe the chocolate buttercream onto each cupcake, top with one Ferrero Rocher chocolate, and sprinkle with crushed hazelnuts.
Notes
Warm the Nutella slightly before filling the cupcakes.
Use dark chocolate for the buttercream to balance the sweetness.
Beat the butter for the full recommended time to create a light, fluffy frosting.
Store cupcakes in an airtight container for up to 3 days at room temperature or 5 days in the refrigerator.
